Explanation for Question 16 From the Writing Section on the 2017 April Sat
Question number 16 asks at this point, 2 the writer's considering adding the following sentence. 3 Should the writer make this addition here? 4 Um, and that details about the beavers lifespan. 5 So looking at this context, we were trying to see if the Beaver's lifespan 6 is relevant or not to the situation that we're talking about. 7 So here, we're talking about how ponds form as a result of dams, 8 how they contain nutrient rich sediment, 9 um, and a variety of plant life, and about the different kinds of wildlife 10 that inhabit beaver ponds. Previously, 11 we were talking about, um, 12 how dams can alter the ecological makeup and generally what their effects 13 are. So what we're asking now is does it make sense to include a 14 detail about the Beaver's lifespan in the context of this discussion of dams? 15 Um, it doesn't really because a Beaver's lifespan is kind of a separate issue. 16 We don't want to confuse the reader by inserting a detail here that doesn't 17 really fit with what the main idea of this paragraph is. 18 So as our choice has a and B the yes, 19 choices are eliminated. Choice C says the detail is not necessary for understanding 20 beavers impact on their ecosystems. This is definitely true. 21 Um, the detail isn't necessary, it doesn't really connect to what we're talking about 22 here. So answer choice C is the correct answer choice D says no, 23 because it does not provide enough explanation of the factors affecting the Beaver's lifespan. 24 Um, this is incorrect because we definitely don't want to hear any more factors 25 affecting the Beaver's lifespan. It's not really relevant. 26 So there's no reason to dive further into something that we barely even want 27 to include in the first place. So choice C is the best fit for 28 question number 16.
